MAT AND METHOD OF MAKING THE SAME.

Application filed Mayan, 1923. Serial No. 641,563.

This invention relates to mats and the method of their manufz-icture and more particularly to mats of the type disclosed in my prior Patent #910,332 granted January 19, 1909.

The mat disclosed in my former patent comprises fibrous cords interwoven upon a perforated framework and one advantage of this construction is that the mat has er:- tending therethrough a number of openings through which dirt may pass. However, the cords lieclosely against the framework and this interferes to some extent with the cleaning of the mat and also gives a relatively hard unyielding wiping surface.

One object of my present invention is to improve upon the construction of this general type of mat by mounting the fibrous cords more loosely upon the framework than has been done heretofore, this construction affording larger openings through the mat and also presenting a relatively larger and more flexible wiping surface.

Itis a further object of my invention to mount the cords loosely upon a framework to the end that the cords and framework may be moved relatively to each other to facilitate cleaning.

In my aforesaid patent the cords are interwoven on a metal framework by being passed from one side to the other of the framework through the perforations thereof, but this mode of Construction has been found to be laborious. It is another object of my invention to improve upon the method of constructing the mat by avoiding interweaving with the framework so that the same may be more quickly assembled.

With these and other objects which will appear as the description proceeds the invention resides in the combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Fig. 1 is aplan view of a mat constructed according -'to my present invention,

7 Fig. 2 is a vertical longitudinal section thereof taken on line 22 of Fig. 1,

Fig. 3 is a diagrammatic plan view showing the relation of the framework, cords, and binders,

Fig. 4 is a diagrammatic view similar to Fig. 2 but showing the behavior of the mat surface under pressure, and

Fig. 5 is a bottom plan View of the invention shown in Fig. 1.

In general my'invention contemplates th use of a framework having perforations through which extend loops formed in cords. the connecting parts of the loops lying under the framework and the loops above the framework. If desired binders may be passed through the loops to prevent them from slipping through the framework.

Referring to the drawings it will be seen that the fran'iework comprises longitudinal bars to which are welded or otherwise secured cross bars 11, said bars being spaced so as to dehne openings which are preferably though not necessarily rectangular.

The outermost of the bars 10 and 1.1 may.

carry an edging 12 similar to that shown in my former patent aforesaid and forming no part of the present invention.

The wiping surface of the mat is afforded by a plurality of coils or loops 13 formed in cords 14 having the ends thereof secured to the frame work in a manner similar to that shown at 15 in Fig. 2. The diameter of the cord 14 is preferably such with respect to the perforations in the framework that the loops fit snugly in the perforations and will be held therein against accidental displacement by friction. However, when desired, binders 16 may be passed through the loops above bars 10 and substantially parallel to bars 11. In order to hold the binders in place the ends thereof may be tied around the loops 13 as indicated at 17 in Fig. 1.

a cord into a series of coils and having secured one end of the cord to the framework I separate the COllS one at a time and pass them through successive openings of the framework. The binders may thereafter be passed through the loops and secured to the loops as already'described. The manner in which this method may be carried out will be understood from an inspection of Figs. 2 and 5.
